It is possible the problem is with the battery, but it actually sounds more like a problem with the park neutral position switch. This is located under the oil pan on the transmission. If it's not making a good connection, then it's not sending signal to allow the starter relay to send power to the starter. Putting the truck into neutral is making the connection so it will start.
It could be wiring from the transmission out to the IPDM and ECM, but it's likely the switch itself.Just Answer does not compensate me for my time and resources, so please rate my answer by using the stars at the top of the page.
